SURGICAL TRUSS.

SPECIFICATION forming part of Letters Patent N 0. 724,808, dated April 7, 1903.

Application filed June 17, 1902.

To all whom it may concern:

Be it known that I, BLANOHARD CHAMBER- LAIN, a citizen of the United States, residing at Bellefontaine, in the county of Logan and State of Ohio, have invented certain new and useful Improvements in Surgical Trusses; and Ido hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same. 7

My invention relates to improvements in trusses for the treatment of hernia or like injuries; and it consists of certain novel features, that will be hereinafter described and claimed.

Reference is had to the accompanying drawings, in which the same parts are indicated by the same letters throughout the several views.

Figure l is a perspective View of the improved truss. Fig. 2 is a rear elevation of the back pad. Fig. 3 shows a section along the line 3 3 of Fig.2. Fig. -l shows a section along the line 4 4 of Fig. 1, and Fig. 5 is adetail showing one 'of the rubber caps removed.

A represents a resilient loop made, preferably, of spring-steel,nickel-plated, and screwthreaded at a". The end A of this loop is bent, as at a, and passes through a hole 17 in the stud B at the rear of the back pad B. This pad is thus swiveled onto the loop A. The fork A is adjustably connected, as by screwing, on the screw-threads a a of-said fork is sprung into recesses c in the stud O at the back of the front pad C.

- material.

This pad 0 is concaved, as indicated in Fig. 4, while the pad B may be either fiator may be specially made of the shape of that portion of the back of the wearer to which it is to be applied.

Over the pads B and O, I place a cap D, preferably of rubber; but it may be made wholly or any part'of buckskin or other soft I prefer rubber, however, especially for the pad 0. These pads B and C are preferably made of aluminium not only on account of lightness, but also because this The end.

metal does not corrode under the influence of excretions from the skin or of the sulfur-gases which discharge from the human body.

By having the pad 0 cup-shaped, as shown, it tends to close the rupture instead of spreading the walls of the same, as happens when a. convex pad is applied. Furthermore, by having an airtight elastic cap over this cupshaped pad the air is imprisoned and forms a soft yielding cushion to the injured part.

Moreover, by having a pad of this character the cap may be readily removed when washed or a fresh one substituted when desired, while the whole truss itself may be thoroughly cleansed at any time. It will be seen that' this truss is readily. applied, occupiesa very small space, and hence will not be apparent below the clothing of the wearer,but may be readily adjusted to fit ,the individual wearer. These and the various other advantages over the trusses now in use will readily suggest -themselves to any truss-maker or any one who has been so unfortunate as to be obliged to wear a truss.

Having thus described my invention, what I claim, and desire to secure by Letters Patent of the United States, is-

1. A truss comprising a loop of resilient material bent over at one end and screwthreaded at the other, with a pad having a stern perforated to receive said bent-over end and revol ubly connected thereto, a combined nut and fork adapted to screw over the other end of said loop, and a pad swiveled to said fork, substantially as described.

2.,A truss comprising a loop of resilient material, having a pad swiveled to one end thereof, a combined nut and fork adapted to screw over the other end of said loop, and a pad swiveled to said fork.

to, a combined nut and fork adapted to screw over the other end of said loop, an aluminium pad swiveled to said fork, and rubber caps adapted to slip over said aluminium pads,

substantially as and for the purpose described.

4. A truss comprising a loop of resilient material having an aluminium pad swiveled to one endthereof, with screw-threads on the other end, a combined nut and fork adapted to screw overthe said screw-threads, an aluminium pad swiyeled to said fork, and rubber caps adapted to slip over said pads, substantially as and for the purpose described. 10

In testimony whereof I aflix my signature in presence of two witnesses.
